Silicon bronze fasteners have become a staple in various industrial, marine, and architectural applications due to their unique blend of strength, corrosion resistance, and aesthetic appeal. Comprising copper, silicon, and other alloying elements, these fasteners provide a balance of mechanical performance and long-lasting durability even in harsh environments.

In this blog, we’ll take an in-depth look into silicon bronze fasteners, including their composition, types, properties, applications, and why Ananka Group is a trusted manufacturer and supplier of these high-performance components.

What Are Silicon Bronze Fasteners?

Silicon bronze fasteners are made from a copper-based alloy consisting of approximately 95–97% copper and 2–4% silicon, supplemented by trace elements such as manganese, iron, and zinc. Depending on the exact composition, this alloy is categorized as UNS C65100 or UNS C65500.

These fasteners offer excellent resistance to corrosion, especially in marine and chemical environments, and maintain high tensile strength along with a distinctive bronze color.
